About this file
This document is a Structure Selection Report Quality Assurance Checklist developed by the Colorado Department of Transportation (CDOT) Staff Bridge Unit for use in 2026. The checklist serves as a standardized quality assurance tool to ensure comprehensive evaluation and documentation of bridge structure selection processes prior to submittal of Final Investment Reports (FIR) to the Region. The checklist requires systematic inclusion of project information spanning cover sheet documentation, executive summary, site description, design features, existing structure analysis, and vicinity mapping. Required sections include right-of-way impact assessment, traffic detour planning, constructability and construction phasing analysis, utility coordination, geotechnical and hydraulics summaries, environmental concerns documentation, and roadway design features including cross-section, vertical alignment, and horizontal alignment specifications. The checklist mandates documentation of structural design criteria, loading specifications including collision and earthquake loads, aesthetic requirements, and potential future widening considerations.
The checklist requires detailed structure selection analysis including rehabilitation alternatives, inspection summaries, load testing requirements, and comparative evaluation of superstructure alternatives such as concrete and steel girder options, along with substructure alternatives including abutment, pier, and wall configurations. Accelerated Bridge Construction (ABC) design evaluation must be included with pre-scoping ABC rating results from CDOT spreadsheet tools. Construction cost analysis for all alternatives, maintenance and durability strategies, corrosive resistance summaries, and service life enhancement strategies must be documented with tier classification. The checklist includes sections for requested variances from CDOT Structural Standards with approval notation and requires sign-off by the CDOT Staff Bridge Unit Leader or designee, confirming approval of all findings, recommendations, and design deviations prior to submission. All figures, appendices, layout drawings, typical sections, quantity summaries, and cost estimate tables must accompany the completed checklist.
